It is worth noting that where interlace is still in use the frame rate is half of the field rate. Countries that have 60Hz mains and that used to be NTSC countries use frame rates based around multiples of 29.97 frames per second. Countries that have 50Hz mains electricity and that used to be PAL countries predominantly use frame rates based on multiples of 25 frames per second. The only difference now is the frame rate. In our now mostly digital and HD/UHD world the same standards are used whether you are in a country that used to be NTSC or used to be PAL. And as most modern cameras are now high definition, digital and most commonly use progressive scan, these standards are no longer applicable to them.Īs a result you will now rarely see these as options in a modern video camera. These standards are now only very, very rarely used for broadcasting. PAL (Phase Alternating Line) and NTSC (National Television Standard Committee) are analog interlaced standards specifically for standard definition broadcasting and transmission. PAL and NTSC are very specifically broadcasting standards for standard definition television.
